Subject: [PATCH 08/23] AArch64: Add MTE CPU feature check support
Date: Wed, 15 Jul 2020 16:44:58 -0300 [thread overview]
Message-ID: <20200715194513.16641-9-luis.machado@linaro.org> (raw)
In-Reply-To: <20200715194513.16641-1-luis.machado@linaro.org>
This patch is a preparation for the next patches implementing MTE. It just adds
a HWCAP2 constant for MTE, creates a new generic arch/aarch64-mte-linux.h file
and includes that file in the source files that will use it.
gdb/ChangeLog:
YYYY-MM-DD Luis Machado <luis.machado@linaro.org>
* Makefile.in (HFILES_NO_SRCDIR): Add arch/aarch64-mte-linux.h.
* aarch64-linux-nat.c: Include arch/aarch64-mte-linux.h.
* aarch64-linux-tdep.c: Likewise
* arch/aarch64-mte-linux.h: New file.
gdbserver/ChangeLog:
YYYY-MM-DD Luis Machado <luis.machado@linaro.org>
* linux-aarch64-low.cc: Include arch/aarch64-mte-linux.h.
